Please refer to the fourth figure, the third preferred embodiment of the present invention. An endoscope image capturing assembly 30 having two or more illumination directions is mainly used in the first embodiment. The difference is that Further, a third light source 39 is included, the illumination direction of which is different from the illumination direction of the first light source 35 by a predetermined angle, and is different from the illumination direction of the second light source 37 by another predetermined angle. In this embodiment, the third light source 39 is different from the illumination direction of the first light source 35 by 3 degrees. The first light source 35 is a plurality of illuminants, and the second and third light sources 37, 39 are singular illuminants. In the present embodiment, the singular or plural illuminators of the light source are merely examples, and the difference in the number is only for the selection of the working state, and is not intended to limit the scope of the present invention. In operation of the second embodiment, the third light source further provides a partial additional illumination range A3 to make the image 7 M405849 within the illumination range clearer. The remaining structure of the third embodiment and the achievable effects are the same as those of the first embodiment, and are not described here. Referring to the fifth to sixth figures, an endoscope image capturing assembly 4 having two or more illumination directions according to the fourth preferred embodiment of the present invention is mainly similar to the first embodiment. The difference is that the first light source 45 is a plurality of light-emitting bodies, and the second light source 47 is a single-numbered light-emitting body. The illumination direction of the second light source 47 is different from the illumination direction of the first light source 45 by 9 degrees. The side of the tube 41 is irradiated. In the present embodiment, the singular or plural illuminant of the light source is merely an example, and the difference in the number is only a selection of the working state, and is not intended to limit the scope of the present invention. The embodiment further includes a side view fitting 51 having a sleeve 52 and a mirror 54. The sleeve 52 is sleeved on the front end of the tube body 41 and corresponds to the image capturing module 43. The sleeve 52 has a transparent window 53. The mirror 54 is disposed in the sleeve 52 and corresponds to the transparent window 53 and the image capturing module 43. The illumination range A2 of the second light source 47 corresponds to In the transparent window 53, the light reflected by the object illuminated by the second light source 47 enters the transparent window 53 from the outside of the sleeve 52, and enters the image capturing module 43 by the reflection of the mirror 54. By taking the image, it can be seen that the illumination range A2 of the second light source 47 is indirectly transferred to the illumination range (® in the ®) of the first light source 45 by the reflection of the light that is incident on the object. The fifth figure does not show the illumination range A2 of the second source of light is reflected in the 8 M405849 state after the reflection of the illumination range of the first source 45, but it can be clearly understood from the fifth figure that the second source, The illumination range A2 of 47 is illuminated by the light reflected by the object to determine the illumination range that can be handed over to the first light source 45. As shown in the sixth embodiment, the embodiment further includes a light source control means 59. In this embodiment, the light source control unit is electrically connected to the first light source 45 and the second light source 47. The opening and closing of the first light source 45 and the second light source 47 are controlled. The light source control means 59 is a hardware circuit or a control software for controlling the light source to be turned on and off. In this embodiment, it is built into the connected operation device 91 in a software manner, and is electrically connected. The first light source 45 and the second light source 47' are operable by a user to select to turn the first light source 45 or the second light source 47 on or off. Such a soft type light source control means is within the conventional Mirror devices are extremely common and are well-known technologies, so they are not described here. In operation of the fourth embodiment, as shown in the fifth figure, the first light source 45 can be turned off and the second light source 47 can be turned on by the light source control means 59. At this time, since the first light source 45 is not illuminated and the second light source 47 is irradiated toward the side, "the light is directly incident on the mirror 54". The light reflected by the object (not shown) illuminated by the second light source 47 enters the transparent view 53 from the outside of the sleeve 52, and enters the image capture module by the reflection of the mirror 54. 43 for the image. Therefore, in the fourth embodiment, when the fourth embodiment is operated, the mirror 54 of the side view component can be prevented from being directly irradiated by the light of the first light source 45, so that the mirror 54 can only reflect the incoming light from the outside. The image capture mode 9 M405849 group 43 is used for image capturing, so that the image can be made clear, and it is not easy to affect the image quality due to whether the mirror surface is dirty or not. In other words, the coating quality of the mirror 54 and the cleanliness of the surface can have a large fault tolerance, which can further reduce the manufacturing cost. In addition, as shown in the seventh figure, the illumination direction of the second light source 47 of the fourth embodiment and the first light source 45 may also differ by 60 degrees, without being limited by 90 degrees.
